The second rail 28 is longitudinally movable relative to the first rail 26, and the second rail 28 can be configured to carry a carried object 36 (e.g. an electronic apparatus, please refer to FIG. 1). At least one space is formed in the carried object 36 and configured to accommodate an electronic component, a power module, a heat sink module, a storage module or the like. Hereinafter, it is illustrative of an example that the carried object 36 accommodates a first upper layer object 38 a, a first lower layer object 38 b, a second upper layer object 38 c and a second lower layer object 38 d. Specifically, each of the objects 38 a, 38 b, 38 c, 38 d can be a field replaceable unit (FRU), but the present invention is not limited thereto. The number of the objects in the carried object 36 is not limited thereto. Wherein, the first upper layer object 38 a and the first lower layer object 38 b are located on right half portion of a space in the carried object 36.

For example, the first end portion 64 a of the third arm 60 is pivoted to the first end portion 64 a of the fourth arm 62 through a second shaft member 65. On the other hand, a third corresponding member 66 is pivoted to the second end portion 64 b of the third arm 60, and the third corresponding member 66 is connected to (such as detachably connected e.g. engaging or plugging) a second connecting member 68 arranged on a rear portion of the first rail 26 of the second slide rail assembly 24. The second end portion 64 b of the third arm 60 is pivoted to the third corresponding member 66. Therefore, the third arm 60 is rotatable relative to the first rail 26 of the second slide rail assembly 24. Moreover, a fourth corresponding member 70 is pivoted to the second end portion 64 b of the fourth arm 62, and the fourth corresponding member 70 is connected to (such as detachably connected e.g. engaging or plugging) a second auxiliary member 72 arranged on a rear portion of the second rail 28 of the second slide rail assembly 24. The second auxiliary member 72 has a height greater than a height of the first rail 26 of the second slide rail assembly 24. Wherein, the second end portion 64 b of the fourth arm 62 is pivoted to the fourth corresponding member 70. Therefore, the fourth arm 62 is rotatable relative to the second rail 28 of the second slide rail assembly 24.

The at least one supporting member 42 includes a first end E1 and a second end E2. The first end El is pivoted to the first rail 26 of the second slide rail assembly 24, and the second end E2 is detachably connected on the first rail 26 of the first slide rail assembly 22. Specifically, the first end E1 and the second end E2 are respectively pivoted to a first connecting base 74 and a second connecting base 76 through a pivot member 73 (the pivot member of the first end E1 and the first connecting base 74 is not shown due to the angle of view). Wherein, the first connecting base 74 is able to be connected to (such as detachably connected e.g. engaging or plugging) a third connecting member 78 of the rear portion of the first rail 26 of the second slide rail assembly 24. Preferably, a gap is formed between the third connecting member 78 and the second connecting member 68. On the other hand, a first mounting member 80 is arranged on the rear portion of the first rail 26 of the first slide rail assembly 22. The second connecting base 76 arranged on the second end E2 of the at least one supporting member 42 is detachably mounted on the first mounting member 80 through a second mounting member 82. For example, the first mounting member 80 can be detachably mounted on the second mounting member 82 by plugging or engaging. Preferably, the second connecting base 76 is able to be detached from the second mounting member 82. Preferably, a gap is formed between the first mounting member 80 and the first connecting member 54. Preferably, in the present embodiment, the at least one supporting member 42 includes a first supporting member 42 a and a second supporting member 42 b connected to the first supporting member 42 a in a stretchable and retractable manner, but the number of supporting members is not limited thereto. Wherein, the first supporting member 42 a has the first end E1, and the second supporting member 42 b has the second end E2.

It is noticed that when the first cable management device 40 and the second cable management device 44 are retracted, a length of the first cable management device 40 (or a length of the second cable management device 44) is slightly less than half of a length of the at least one supporting member 42. In other words, when the first cable management device 40 and the second cable management device 44 are retracted, a gap is formed between the first cable management device 40 and the second cable management device 44. Therefore, bending radius for cable managing of the first cable management device 40 and the second cable management device 44 can be reduced, in order to facilitate managing cables.

As shown in FIG. 4, a first blocking feature 84 is arranged on one of the first arm 46 and the second arm 48 of the first cable management device 40. Hereinafter, it is illustrative of an example that the first blocking feature 84 is arranged on the first arm 46. Wherein, the first blocking feature 84 and the first arm 46 can be integrally formed in one piece, or the first blocking feature 84 can be a separated component fixedly mounted on the first arm 46. Preferably, a second blocking feature 86 is arranged on one of the third arm 60 and the fourth arm 62 of the second cable management device 44. Hereinafter, it is illustrative of an example that the second blocking feature 86 is arranged on the third arm 60. Wherein, the second blocking feature 86 and the third arm 60 can be integrally formed in one piece, or the second blocking feature 86 can be a separated component fixedly mounted on the third arm 60.

When the second rail 28 of the first slide rail assembly 22 is located at a retracted position P1 relative to the first rail 26, the first arm 46 and the second arm 48 are closed to each other and are in a closed state. When the second end E2 of the at least one supporting member 42 is connected to the first rail 26 of the first slide rail assembly 22, the at least one supporting member 42 blocks the first blocking feature 84, to further block the first cable management device 40. Preferably, when the second rail 28 of the second slide rail assembly 24 is located at a retracted position relative to the first rail 26, the third arm 60 and the fourth arm 62 are closed to each other and are in a closed state. The at least one supporting member 42 blocks the second blocking feature 86, to further block the second cable management device 44. As such, the first cable management device 40 and the second cable management device 44 are arranged to close a rear space behind the first slide rail assembly 22 and the second slide rail assembly 24. In addition, when the first arm 46 and the second arm 48 are closed to each other and are in the closed state, the at least one supporting member 42 is configured to support the first cable management device 40 (such as support a bottom portion of the first cable management device 40). When the third arm 60 and the fourth arm 62 are closed to each other and are in the closed state, the at least one supporting member 42 is configured to support the second cable management device 44 (such as support a bottom portion of the second cable management device 44).

It is noticed that when the at least one supporting member 42 blocks the first blocking feature 84, the first upper layer object 38 a or the first lower layer object 38 b is blocked by the first cable management device 40 from being detached from the carried object 36 to the rear space behind the first slide rail assembly 22 and the second slide rail assembly 24 (please refer to FIG. 1). Similarly, when the at least one supporting member 42 blocks the second blocking feature 86, the second upper layer object 38 c or the second lower layer object 38 d is blocked by the second cable management device 44 from being detached from the carried object 36 to the rear space behind the first slide rail assembly 22 and the second slide rail assembly 24 (please refer to FIG. 1).

As shown in FIG. 5 and FIG. 6, when the second end E2 of the at least one supporting member 42 is detached from the first rail 26 of the first slide rail assembly 22, the at least one supporting member 42 is able to be rotated through the first end E1 in order to be deflected backward, such that the at least one supporting member 42 no longer blocks the first blocking feature 84 (and the second blocking feature 86), and such that the first cable management device 40(and the second cable management device 44) is able to be rotated to be deflected backward to open the rear space behind the first slide rail assembly 22 and the second slide rail assembly 24. It is noticed that, in the present embodiment, the second end E2 of the at least one supporting member 42 is unmounted from the second mounting member 82 through the second connecting base 76, such that the second end E2 of the at least one supporting member 42 is detached from the first rail 26 of the first slide rail assembly 22. For example, the second connecting base 76 includes a fastening member 88 (or a protrusion) able to be mounted in a space 90 of the second mounting member 82. Preferably, an elastic member 92 (e.g. an elastic piece) is operably connected to one of the second mounting member 82 and the second connecting base 76 (for example, the elastic member 92 is operably connected to the second mounting member 82). Wherein, the fastening member 88 is blocked in the space 90 through the elastic member 92 being located at an engaged position, and the elastic member 92 is operable to be located at a disengaged position (please refer to FIG. 5), in order to allow the fastener 88 to be detached from the space 90, such that the second end E2 of the at least one supporting member 42 is unmounted from the second mounting member 82 through the second connecting base 76, to further be detached from the first rail 26 of the first slide rail assembly 22. Alternatively, the second end E2 of the at least one supporting member 42 is able to be unmounted from the first mounting member 80 through the second mounting member 82, such that the second end E2 of the at least one supporting member 42 is detached from the first rail 26 of the first slide rail assembly 22.

As shown in FIG. 6, when the at least one supporting member 42 is rotated through the first end E1 to be deflected backward substantially by an angle of 90 degree and the first cable management device 40 is rotated to be deflected backward by an angle of 90 degree substantially, the first upper layer object 38 a and the first lower layer object 38 b are no longer blocked by the first cable management device 40, in order to allow the first upper layer object 38 a and the first lower layer object 38 b to be detached and moved along a rear direction D from the carried object 36. Wherein, the rear direction D and a transverse direction are perpendicular to each other. A height direction and the rear direction D are perpendicular to each other. The height direction and the transverse direction are perpendicular to each other.

As shown in FIG. 6 and FIG. 7, when the at least one supporting member 42 is rotated through the first end E1 to be deflected backward substantially by an angle of 90 degree and the second cable management device 44 is rotated to be deflected backward by an angle of 90 degree substantially, the second upper layer object 38 c and the second lower layer object 38 d are no longer blocked by the second cable management device 44, in order to allow the second upper layer object 38 c and the second lower layer object 38 d to be detached and moved along the rear direction D from the carried object 36.

As shown in FIG. 1 and FIG. 8, when the carried object 36 is moved relative to the first rail 26 from the retracted position P1 along a front direction (e.g. a direction opposite to the rear direction D) to an extended position P2 through the two second rails 28 of the two slide rail assemblies 22, 24, the first arm 46 and the second arm 48 of the first cable management device 40 are extended relative to each other and are in an extended state, and the third arm 60 and the fourth arm 62 of the second cable management device 44 are also extended relative to each other and are in an extended state.
